To all whom t may concern?,

Beit known that we, BoNIEAoE R. KLOEB and JOSEPH A. KLOEB, citizens of the United States, residing atHoboken, in the county of Hudson and State of New Jersey, vhave invented certain new-and useful Improvements in Gaseous-Fuel Burners, of which the following is a specification.

i This invention relates to gaseous fuel burners of the type particularly adapted for converting a liquidhydro-carbon fuel into a gas ywhich may be ignited and burned with a blue liame. v

One of the objects of the invention is to provide la novel burner construction that may be conveniently used in stoves and furnaces for cooking and heating purposes.

Another object of the vinvention is to prol vide a simple and practical construction that may be. readily and economically. manufactured and assembled thereby materiallyenhancing the value ofthe invention from a practical and commercial standpoint.

A further object of they inventionis to provide a. simple andV practical arrangement of parts which thoroughly vaporizes the liquid Jruel andinsures perfect combustiondue to the fuel'being adequately vaporized.

With the above and other objects in view which will more readily appear as the nature of the invention is better understood, the i same consists in the novel construction, combination and arrangement of parts, herein- `after more fully illustrated and claimed.

A preferred land practical embodimentof they invention isshown inthe accompany' ing drawings, in which:

Figure 1 is a side elevationofthe Vimproved burner construction. 40 Figure 2 is a vertical sectional view thereof.

FigureK 3 is*` a horizontal sectional view taken onthe line 3--3 of Figure 1.

Figure 4 is a. cross sectionalview vtaken on the line lr-f4 of Figure k1.`

Similar reference characters designate correspondngparts throughout the several figures of the drawings.'y

According to the embodiment of the in- `vention shown in the drawings, it is proposed to provide a suitable base or stand 1 'having the side walls Q, thereby` to` also serve -as a flash pan for startingv purposes.

ISupported on the said base is a novel burner device designated generally as B and a gen- `xerator G, the same being arranged lto` be heated by the flame from the-burner to'va'- porize the fuel prior to Carburation land, dei livery to the burner. i .e Referring more particularly'to the `details of construction, it will'be observed thatl the generator G is preferably o f ring-like or annular formation having the interior generating chamber 3 communicating as at 4 with a fuel supply pipe 5, and also having a `vaporized fuel youtlet 6 which communicates with a vapor feed pipe 7 of angular forma.

tion, and having inits-upright portion, the I discharge port or vent 8 y for :supplying the fuel vaporto the burner.

, For the purpose of supporting the generator in such a manner that the level of liq,`-

Quid fuel, fed in` by gravity through the 'supply pipe 5, will lnot rise too high thereby to occupy all the space in the generator andwork its way up into/the feed pipe 7 the said generator maybesupported in an inclined position and to that end the postk or support 6a may be employed.

The burner B, is preferably made in two coinplemental sections 9 and 10, and is `of substantially T-shaped formation, kthat is, it l comprises a.l relatively horizontally disposed hollow body or head which provides a mixing chamber 11 and a depending shank `"which formsv a generator heating flue F.,

This head` is closed atv oneend, asatk l2, and

a super-heater tube 14, while thesides of the sections 9 and 10 may be provided with the flame openings Bf to permit the escape of the nopen at the opposite end, as at 13, to receiveiiame when the `burner is in operation; andr as will alsobe observed from Figures land 2, the lower parts 9a and 10 of said sections which constitute the shank of thev bodyprovide the relatively vertical heatingrfiue'F which projects down through the central v opening ofthe generator ring and rests'on the base 1. vAdjacent the lower edge of the flue F openings F are provided for the purpose of permittingy the escape of ame thereby to envelop the generatorI after the burner is in operation7 and, insuring the continuance of the vaporization of the fuel.

The superheater tube 14 is cut away at its inner end, to provide the discharge mouth 14a, and may be supported on a lug 14h or its equivalent on the burner casing, while th opposite end thereof may be held securely in the opening` 13 by a. set screw 13l or the like. As clearly indicated in Figures 1 and 2 the open receiving end of the superheater tube 14 projects beyond one end of the b l and terminates in spaced relation to the upright part of the vaportube T, so that the vaporjet issuing from the orifice 8 will carry with it outside :air as it is projected into the tube 14 thereby providingaproperly carbureted mixture within the tube 14. lifter xthe burner is in operation for a Short period the tube 14 becomes red hot and the fuel vapor becomes superheated, thereby cracking the molecules of fuel vapor into a very fine state which insures combustion without carbon, even when relatively low hydro-carbon fuel oils are used. By .reasoniof the manner in which the tube 14 is mounted it may be shifted with reference to the feed pipo to thereby regulate the amount of air mixed with the vapor.

lllhen'it desired to start the operation of the device a small quantity of priming` fuelisy placed in the vpan provided by the base 1 and walls 2 thereof. and 'the liquid fuel in the generator G will become vaporize'd and gradually rise into the pipe T from whence it will be discharged t1 orifice 8 in jet form into the superheater tube 14 after being mixed with air in transit from the'oritice to the tube 14. After passing. through the tube 14 toward the truncated discharge end 142L at the opposite end ofthe burner B, the vapor makes its way to the mixing chamber 11 and. when sufficient quantity is available. it will be ignited from the flame in the flash pan and the'burner proceeds. to operate. As the heat of the burner becomes more intense the generation of vapor in the generator G becomes more rapid and the heating effect of the burner becomes greater'. After the superheater tube 14 becomes red hot the fuel vapor becomes especially available for combustion and burns with a blue flame without leaving a carbon deposit.

1t will, of course, be understood that the burner may be supported above the flash pan in any suitable and practicable maniier, but in the embodiment shown the annular collar 17 yon the flue F and the depending` leg or strut'll s traddling over the inlet end of the generator as at 19, serves to hold the burner in proper position.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be nrough the weies understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
